light enters from air to glass having refractive index 1.50 wwhat is the speed of light in the glass ?
Answers
Let X be the speed of light in glass
1.5 = (3x10^8) / X
X = (3x10^8) / 1.5
= 2 x 10^8 m/s
Hey Buddy ❤
Your Answer -
Given :
Speed of light in vacuum, c = 3 × 10^8 m/s
Refractive index of glass = 1.50
Formula :
Refractive index of a medium = Speed of light in vacuum/Speed of light in the medium
Solution :
Speed of light in the glass
= Speed of light in vacuum/ Refractive index of glass
=3 × 10^8/1.50
= 2x 10^8 ms-1
Glad To Help :D
